Cataclean Fuel & Exhaust System Cleaner, Automotive Additive, Catalytic Converter Restorer, 16 oz (Pack of 2)

My service engine light was on and was told it's related to my catalytic converter. I followed instructions on using this product and the light has now been off for serval months. Keeping my fingers crossed that it's going to continue. I was quoted over $3,500 for replacement of my catalytic converter because my vehicle has two converters. If you have the same issue you should at least give this a try.

There are only 3 Catylitic Converter Cleaners on the Market commercially %26 this is considered the BEST comparable to those used in F1 racing. It did wonders for my Minivan!!! Never used any before now %26 it really solved the problem; DO EXACTLY WHAT IT SAYS ON DIRECTIONS!!...is what my mechanic said, I DID %26 he was spot on right.

I had to use two bottles but it turned by check engine light off and I passed emissions testing.

I suggest you run this in every engine you have. I run it as directed and it keeps the smog lights off.

Been using this for about a year so far everything seems to be good on my catalytic converter issue would buy again

The thing was very good and it was worth it for me and worked out very well

Followed instructions and check engine light is Off. Now I have an extra bottle.

Cleans as stated.

so far so good on keeping the cat code from coming on in my 1996 4 Runner

This was delayed in shipping and did not arrive in time to use for a trip. We added it later, and so far have not noticed any difference in the car's performance but will give it time to work before making a final decision. In the future, however, we will just get it at AutoZone where we can pick it up as needed and not have to wait for delayed shipping.
